Ass.-Prof. Dr. Sepideh Hatamikia was invited to write a review paper in ‘Physics in Medicine & Biology’ journal with the title of ‘Source-detector trajectory optimization in cone-beam computed tomography: a comprehensive review on today's state-of-the-art’. This is the first review paper in this growing research area (customized CBCT source-detector trajectories).
Cone-beam computed tomography (CBCT) imaging is becoming increasingly important for a wide range of applications such as image-guided surgery, image-guided radiation therapy as well as diagnostic imaging such as breast and orthopaedic imaging. One important feature of interventional imaging is that prior knowledge of patient anatomy such as a preoperative CBCT or prior CT is commonly available. This provides the opportunity to integrate such prior information into the image acquisition process by customized CBCT source-detector trajectories. The recently developed robotic CBCT C-arms with additional degrees of freedom provide the possibility to largely expand the scanning geometries beyond the conventional circular source-detector trajectory. This recent development has inspired the research community to innovate enhanced image quality by modifying image geometry, as opposed to hardware or algorithms. Because of the great practical value and the increasing importance of CBCT imaging in image-guided therapy for clinical and preclinical applications, this paper focuses on the review and discussion of the available literature in the CBCT trajectory optimization field. This paper is the first study that provides an exhaustive literature review regarding customized CBCT algorithms and tries to update the community with the clarification of in-depth information on the current progress and future trends.
